THOR H. LANGE, OF BRIDGEPORT, CONNECTICUT, ASSIGNOR TO WHITING MANUFAC- TUBING COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.

LAMP.

To all whom it may concern:

Be it known that I, THOR I-I. LANGE, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented a certain new and useful Improvement in Lamps, of which the following is a specification.

The invention relates to lamps adapted to burn alcohol or hydrocarbons for heating purposes, and is designed more especially for service with tea or coffee urns, chafing dishes and analogous utensils.

The object of the invention is to provide a lamp of this character which shall be simple and economical in construction, not liable to derangement, and in which the flame may be easily controlled or regulated from various points adjacent to the lamp.

The invention consists in certain details of construction by which the above objects are attained, to be hereinafter described.

The accompanying drawings form a part of this specification and show an approved form of the invention.

Figure 1 is a side elevation of the improved lamp, showing its position relatively to a stand and kettle represented in dotted lines. The remaining figures are on a larger scale and show the lamp alone. Fig. 2 is a plan view. Fig. 3 is an elevation of the side opposite to that shown in Fig. 1, and Fig. 4 is a vertical axial section taken on the line 4 i in Fig. 3.

Similar letters of reference indicate the same parts in all the figures.

A is the cylindrical body portion of the lamp, formed of thin metal and having an annular offset or shoulder A by which it is supported in any suitable opening or socket provided for the purpose. It has a neck A terminating at the top in a narrow ring or collar A from which a bracket A projects laterally having a fixed vertical pin A serving as a pivot for a horizontally swinging cover B.

The cover is a plane circular disk of metal having a projection B matching the contour of the bracket A and receiving the pin A The cover is slightly larger in diameter than the collar A and in the closed position completely overlies the opening therein.

On the cover at about the center is riveted a vertical stud B receiving a loose sleeve C to which is secured a horizontally-extending rod 0 terminating in a handle C by which Specification of Letters Patent.

edge of the bracket A and serve as a stop in the closed position, and a lug A on the bracket serving as a stop in the fully open position.

Any preferred form of wick may be employed; that shown consists of a perforated shell D received in the body A, having a filling D of asbestos or the like, with a cover of wire cloth D and provided with an arm D received in a notch a in the collar A, by which it may be removed to permit the introduction of alcohol or other spirits into the body portion A.

Upon the pin A is a head A of large area to resist vertical movement of the cover relatively to the body, and thus to permit the whole to be lifted and carried by the rod C without danger of derangement, and the loose connectionof the rod to the stud B permits the cover to be manipulated by the rod from any position in which the latter may be placed, as for example, in either of the spaces between the standards indicated in dotted lines in Fig. 1 as supporting the kettle.

By moving the cover to vary the area of the exposed portion of the wick, the flame is readily adjusted or extinguished, and, as above stated, the movement may be made with the rod at any angle relatively to the lamp.

The lamp is especially intended to be made of silver for service with tea sets and the like, made of similar costly material, and it is essential that the amount of such material used in the lamp be as small as practicable and that the construction shall require few parts, simply but efficiently joined and capable of withstanding the heat of the flame. The improved lamp attains these desired ends successfully.

I claim:

1. In a device of the character set forth, a lamp-body having an opening at the top, a cover pivotally connected to said body at one side of said opening and constructed to swing horizontally to open or close said opening, an operating rod loosely pivoted upon said cover and coacting means on said cover and lamp-body arranged to arrest the movement of said cover in the fully opened and closed positions of the latter.

2. In a device of the character set forth, fully opened and closed positions of the a lamp-body having an opening at the top, latter. a cover pivotally connected to said body at In testimony that 1 claim the invention one side of said opening and constructed to above set forth I affix my signature, in swing horizontally to open or close said presence of .tWo Witnesses. opening, an o eratin rod pivotall connected to said cover it or near the center I THOR LANGE' thereof, an arm on said cover, and stops on Witnesses: said body arranged to be struck by said arm ROBERT W.
